Services

In the industrial sector, tube bending services are a key part of the manufacture of high-performance metal structures, machinery and components. Companies such as COES SL have perfected this technique, offering bending, forming and welding solutions that combine precision, durability and an impeccable finish.

Working with metal pipes requires not only experience, but also advanced technology to maintain material properties and ensure exact geometry at each radius. Whether for applications in automotive, construction, furniture or industrial installations, tube bending is synonymous with structural efficiency and functional aesthetics.

Tube bending is the main service within the COES SL catalog. This process consists of modifying the geometry of the tube without compromising its integrity or cross-section. In other words, it is about bending the material to the desired shape, maintaining a continuous internal flow and without critical deformations.

COES SL uses state-of-the-art CNC bending machines, capable of working with steel, iron, aluminum and copper in different diameters and thicknesses. These machines guarantee full control over the bending parameters, achieving identical parts even in long production runs.

The technical team monitors each phase of the process to ensure that tolerances are minimal and that the resulting parts meet the customer’s specifications. From small radii for compact structures to wide curvatures for driving systems, the result is always a functional, robust piece with an impeccable industrial aesthetic.

In addition, cold bending of tubes offers significant advantages over other methods: it prevents thermal alteration of the material, maintains mechanical strength and minimizes post-finishing costs. That is why this service is in high demand in industries where precision and strength are determining factors.

Complementing bending, tube forming allows for even more complex parts adapted to the design and assembly needs of each customer. This process includes operations such as flaring, fluting, crushing or widening, which modify the sections of the tube to facilitate its assembly or improve its structural behaviour.

COES SL has specific machinery to carry out different types of forming with micrometric precision. Thanks to automation and digital programming of the machines, individual designs can be reproduced with absolute repeatability.

Forming is essential in industries such as automotive, air conditioning, boilermaking or industrial machinery, where tubes must not only bend, but also adapt to a wider technical whole. In many cases, a properly formed part reduces the number of welds required and improves assembly efficiency on the production line.

In short, tube forming is the art of transforming a rigid material into a functional and optimized solution, while maintaining the mechanical properties of the metal and offering professional aesthetics.

Within tube bending services, welding is the final phase that ensures the integrity of metal structures. At COES SL, welding is carried out both manually and robotically, depending on the characteristics of the project and the type of material.

In the case of carbon steel, the company uses TIG, MIG and arc processes that guarantee a firm, porous-free bond with a high tensile strength. COES SL welders have extensive experience in handling different thicknesses and geometries, always complying with the quality and safety regulations applicable to the metallurgical sector.

Robotic welding, on the other hand, is applied when large production volumes or absolute precision in the repetition of beads are required. This type of welding not only speeds up manufacturing times, but also improves the homogeneity of parts and reduces the possibility of human error.

The combination of bending, forming and welding allows COES SL to offer a comprehensive service that covers from the initial design to the delivery of the finished product, ready for assembly or integration into other systems.

In an increasingly demanding market, COES SL is committed to technological innovation and quality control at every stage of the process. Each production batch goes through a rigorous dimensional and visual control to ensure that the parts meet the tolerances required by the customer.

In addition, the company maintains a continuous commitment to process improvement and the training of technical personnel, thus ensuring maximum efficiency and reliability. The use of CAD/CAM software in the design of curved and formed parts allows you to anticipate results, optimize materials and reduce set-up times.

The tube bending services offered by COES SL have applications in a wide variety of industrial sectors:

• Automotive: structures, exhausts, stabilizer bars.
• Air conditioning and refrigeration: gas circuits , heat exchangers, coils.
• Metal furniture: chairs, tables, decorative structures.
• Construction and engineering: handrails, railings, conduits and structural supports.
• Energy and machinery: hydraulic pipes, frames, ventilation systems.

Each project is approached in a personalized way, ensuring that the design and execution are adjusted to the technical, aesthetic and resistance needs required by each client.

Tube bending services are much more than an industrial operation: they represent the union of mechanical precision, technological innovation, and human expertise. At COES SL, every bent, formed or welded tube is the result of years of specialization and commitment to quality.

Thanks to its technical capacity and the versatility of its equipment, COES SL has established itself as a benchmark in customised metal solutions, offering a comprehensive service that goes from the initial idea to the final part ready to be assembled.

Metal takes shape, precision becomes art, and experience translates into results. This is how COES SL brings each project to life, curving the future with solidity and industrial style.
